Status as a "Metal Hero" series
While it is commonly known that Kabutack and Robotack are part of the Metal Hero series, there is much debate on whether or not they are part of the Metal Heroes series.
During Super Hero Taihen, a list is presented showing each of the previous Metal Hero series, and Kabutack and Robotack are shown. However, Moerro!! Robocon is also shown along with the other shows, possibly meaning the list was not for all the Metal Hero shows that have aired, just the shows that were aired after the Kamen Rider series ended.
The Super Hero Taisen Z showed another list of all Metal Hero series, and Kabutack and Robotack are not shown. However, Taisen Z is the only official media that did not include Kabutack and Robotack, make itself a doubtful source.
The recent recognization is the Toei Official Tokusatsu Youtube channel, started on November 2017 it uploaded the Tetsuwan Tantei Robotack series every week to cerebrate its 20th anniversary under the subtitle The 90's Metal Hero Series.
